This is called "multilogin". You sure can bookmark them, but if you ever happen to get logged out and then you log back into them in a different order, you'll find that the 0/1/2 really do refer simply to "the <N>th Google account I signed into", so your bookmarks might not work.
Yeah, I would just log out of all of them and log back in with the desired order if that happened. That doesn't happen very often though.
